Hello arif
I m pawan gupta
I dont know what is your problem actully but as you told that your jsp page in not getting compiled so do one thing that
first of all put you bean in a package that is
put the following line in your jsp as first line of program
package inf;
and then compile your Java bean
remember that their should be a folder namedinfinside classes folder means structure shold be
\WEB-INF\classes\inf
and then the use it in your jsp page as
<jsp:useBean id="your bean id" classes="inf.UserBean" />
might be it will work
becoz i bean should alway be inside a package;

Dear Mr Grpta
Thnx for trying to help. when i was restructuring the code, i find that, i was trying to use <jsp:use Bean... /> inside <% %> jsp block. then i remove the block and compile the UserBean class inside a package named "com". as u say, i use it in \WEB-INF\classes\com directory and try to run the jsp page. then previous error was gone but it still not run. it say now..
